Abstract

L'invention a pour but d'obtenir un bouchon moulé en une seule pièce de matière thermoplastique qui puisse se démouler correctement avec un anneau d'inviolabilité subissant au débouchage une séparation ou une rupture efficace. L'anneau d'étanchéité, prévu à la base de la jupe du corps de bouchon, se compose d'une jupe extérieure 4 et de segments intérieurs 5 écartés de la jupe 4 à laquelle chacun des segments est relié par ses extrémités 6 orientées obliquement par rapport à la direction radiale dans un certain sens de façon à se replier contre la jupe de l'anneau au démoulage et au bouchage mais à être retenu par la contre-bague du col de récipient au débouchage en provoquant alors la séparation ou la rupture de l'anneau d'inviolabilite en des points de moindre resistance prévus à la fabrication du bouchon. L'invention s'applique aux bouchons à vis ou encliquetables.The object of the invention is to obtain a stopper molded in a single piece of thermoplastic material which can be demolded correctly with a tamper-evident ring undergoing, on unblocking, effective separation or rupture. The sealing ring, provided at the base of the skirt of the stopper body, consists of an outer skirt 4 and inner segments 5 spaced from the skirt 4 to which each of the segments is connected by its ends 6 oriented obliquely. relative to the radial direction in a certain direction so as to fold up against the skirt of the ring on demoulding and capping but to be retained by the counter-ring of the container neck on unblocking, then causing separation or rupture the tamper-evident ring at points of least resistance provided for in the manufacture of the stopper. The invention applies to screw or snap-on caps.
